Feeling Out of It When Driving

I have not been able to drive for the last 3 weeks.  It all started when I was driving with my husband in the car, and all of a sudden I felt like I was going to faint. I pulled over on the highway.  My heart was beating really hard and I was sweating.  I am not sure though, if this was a cause or a result of me having to pull over.  Ever since then, I have not been able to drive because every time I get in the car I feel out of it, I am lightheaded and about to faint. I feel this way when I am a passenger in the car.  My husband and I don't usually have to go on the highway, but we did today, and the speed of the highway made my symptoms get a lot more exaggerated.  The best way I can describe the feeling is that it felt like I was on a rollercoaster with no seatbelt and no sides on the car.  Like the car was going to fly off the road at any second. I went to the ER the 2nd time this happened when I was driving and they did tons of tests..EKG, pregnancy test, CT scan, chest x-rays, and found nothing. I made an appt with my primary care physician and she thought it might be panic attacks. I have been on Zoloft for 2 weeks and seen no improvement.  I started thinking they probably weren't panic attacks because this sensation occurs every time I am in a car, from the time the car is moving, to the time it stops.  I made an appt with an ENT to get tested for Vertigo, although I have never heard of someone getting vertigo only when they are driving.  If anyone has ANY ideas, please let me know because I am desperate for help.  It is very frustrating not being able to drive.

Greetings,

You may have a problem with your eyes. Type "vertical heterophoria syndrome" into a google search. The first site that comes up should be from vision specialists of Birmingham MI. Check out the symptoms and testimonials and see if you can relate. Then give them a call and the rest is up to you. It helped me. Good Luck.

Lognum,
I am going to look at the site now.  Can you believe that I am not far at all from Birmingham, Mi?  I will check it out immediately. Thank you so much for your response.

Mcsnick,

I read your post with your symptoms. I'm going through the identical issue right now. I've already gone through various tests. My biggest issue is driving on the highway. Have you had any luck with a diagnosis?

Thanks and I hope you're feeling better!
